Description

Chemical sampling device

Technical Field

Embodiments relate to chemical sampling devices.

Background

Companies that process chemicals harmful to the human body, for example, companies that manufacture chemicals, such as companies that manufacture semiconductors, LCDs, OLEDs, pharmaceuticals, paints, etc., use various types of chemicals for a single process or a plurality of unit processes.

In general, chemicals are supplied to a main tank by means of a tank truck or the like, and some chemicals stored in the main tank are separated and stored in a plurality of sub-tanks, so that the chemicals may be sequentially supplied to a single unit process or separately supplied to a plurality of unit processes.

As another example, when the amount of the chemical is small or when the tank is not available due to the nature of the chemical, the chemical may be directly supplied to the sub-tank by means of a drum, a bottle, or the like.

If the chemicals are contaminated in tankers, drums, bottles, storage tanks, pipes, etc., defects may occur during the unit to which the chemicals are supplied.

Therefore, it is necessary to control the contamination level of chemicals at an appropriate level at a main location of each tank car, drum, bottle, storage tank, pipe, etc. Accordingly, a sampling device capable of sampling chemicals at a main location has been developed.

The sampling apparatus in the related art includes a sampling chamber, a plurality of sampling lines respectively connected to a plurality of main locations and configured to supply chemicals into sampling bottles accommodated in the sampling chamber, and valves respectively installed in the plurality of sampling lines.

The operator can perform the following sampling operation using the sampling apparatus in the related art.

For example, an operator directly opens the cap of the sampling bottle, loads the sampling bottle into the sampling chamber, and fills the sampling bottle with chemical by operating a valve in the sampling line (which is connected to the main location where the chemical is sampled). In addition, the operator unloads the sample bottle filled with the chemical from the sampling chamber, directly closes the cap of the sample bottle, and transports the sample bottle to a site for analyzing the contamination level of the chemical.

Generally, as described above, the sampling operation is mostly manually performed by an operator.

Therefore, there is a problem in that the possibility of contamination of chemicals during the sampling operation is high due to negligence of an operator or the like. In addition, there is a problem in that the possibility of the operator being exposed to the chemicals is high.

These problems are likely to occur during the process of an operator directly opening or closing the cap of the sampling bottle.

Meanwhile, if the chemicals are contaminated during the sampling operation, the reliability of the analysis result of the degree of contamination of the chemicals may be lowered. Furthermore, it may be inconvenient for an operator to prepare the highest level of protection safety equipment and wear or take off the safety equipment to protect the operator.

FIG. 1 is a view of a chemical storage facility.

Referring to fig. 1, a chemical storage facility 1 may include ACQC (automatic cleaning quick coupler) units 2, a first chemical storage tank 3, a chemical distribution device 4, and a plurality of second chemical storage tanks 5 and 6.

ACQC unit 2 may deliver chemical supplied from the tank car to the first chemical storage tank 3. The chemical distributing device 4 may separate some of the chemicals stored in the first chemical storage tank 3 and supply the chemicals to the plurality of second chemical storage tanks 3 and 4.

The chemical sampling apparatus 10 may be connected to a plurality of chemical storage tanks 3, 5, and 6 through a plurality of sampling lines L1, L2, and L3.

In the present embodiment, the configuration in which the sampling lines L1, L2, and L3 are connected to the chemical storage tank has been described, but the present disclosure is not necessarily limited thereto. The sampling lines L1, L2 and L3 may be connected to all types of chemical supply sources, such as tank trucks, drums, bottles, storage tanks, pipes, etc. that supply, store or transport chemicals.

Furthermore, three sampling lines L1, L2 and L3 are shown, but the disclosure is not necessarily limited thereto. The number of sampling lines may be one, two or four or more depending on the number of chemical supplies.

The switching valve V and the pump P may be installed in each of the plurality of sampling lines L1, L2, and L3.

The pump P is used to deliver chemicals through the sampling lines L1, L2 and L3, but the invention is not necessarily limited thereto. A gas supply may be provided to deliver chemicals from the chemical supply to the sampling lines L1, L2 and L3 by supplying a gas (e.g., nitrogen or air) to the chemical supply.

The housing 100 constituting the chemical sampling apparatus 10 may be disposed on the chemical dispensing device 4, but the present disclosure is not necessarily limited thereto.

Fig. 2 is a perspective view of a chemical sampling apparatus according to an embodiment of the present disclosure, fig. 3 is a perspective view illustrating an inside of a housing shown in fig. 2, and fig. 4 is a perspective view illustrating a state in which a first vertical partition wall and the housing shown in fig. 3 are removed.

Referring to fig. 2 to 4, the chemical sampling apparatus 10 according to the embodiment of the present disclosure may include a housing 100, a bottle holding unit 200, a cap separating/coupling module 300, and a bottle transporting unit 250. The chemical sampling apparatus 10 may further include a discharge module 500 and a discharge module transfer unit 600.

The housing 100 has an inner space and a first inlet 101 connected to the inner space.

For example, the first inlet 101 may be opened or closed by a first door 103 hingedly coupled to the housing 100.

Thus, the operator may close the first inlet 101 after loading the sampling bottle B into the inner space of the housing 100 through the first inlet 101.

The sampling bottle B may be loaded into the inner space of the housing 100 in a state where the cap C is coupled to the sampling bottle B.

The inner space of the case 100 may be partitioned into a first-first inner space A1-1, a first-second inner space A1-2, a second inner space A2, and a third inner space A3 by a plurality of partition walls 110, 120, and 130.

The plurality of partition walls 110, 120, and 130 may include a first partition wall 110 extending in a horizontal direction, and a second partition wall 120 and a third partition wall 130 extending in a vertical direction. The first, second and third partition walls 110, 120 and 130 are each coupled and fixed to the housing 100.

The first-first internal space A1-1 may be a space defined by an inner surface of the case 100, an upper surface of the first partition wall 110, and one surface of the second partition wall 120. The first-first internal space A1-1 may be partitioned from the first-second internal space A1-2 by the second partition wall 120.

The first inlet 101 may be formed in a sidewall of the housing 100, which adjoins the first-first inner space A1-1.

The first-second internal space A1-2 may be a space defined by an inner surface of the case 100, an upper surface of the first partition wall 110, another surface of the second partition wall 120, and one surface of the third partition wall 130. A plurality of sampling lines L1, L2, and L3 and a cover separation/coupling module 300 may be disposed in the first-second internal spaces A1-2. Accordingly, the chemical sampling operation and the cap separating/coupling operation can be performed in the first-second internal spaces A1-2.

A plurality of vent holes 105 may be formed in a sidewall of the housing 100, which adjoins the first-second internal spaces A1-2.

The exhaust module 107 may be coupled to a plurality of vent holes 105. The exhaust module 107 may exhaust the chemical fumes generated in the first-second internal spaces A1-2 to a chemical purifying facility (not shown) or the like.

The exhaust module 107 may include a blower, but the present disclosure is not necessarily limited thereto.

The second internal space A2 may be a space defined by an inner surface of the case 100, a lower surface of the first partition wall 110, and one surface of the third partition wall 130. The second internal space A2 may be partitioned from the first-second internal spaces A1-2 by the first partition wall 110.

The third internal space A3 may be a space defined by an inner surface of the case 100 and the other surface of the third partition wall 130. The third internal space A3 may be partitioned from the first-second internal spaces A1-2 by a third partition wall 130. The third internal space A3 may be a space separated from the second internal space A2, but the present disclosure is not necessarily limited thereto. The third internal space A3 may be a space connected to the second internal space A2.

The second inlet 121 is formed in the second partition wall 120. The second inlet 121 is a passage through which the sampling bottle B loaded into the first-first internal space A1-1 can be transferred to the first-second internal space A1-2.

For example, the second inlet 121 may be opened or closed by a second door 123 hingedly coupled to the second partition wall 120.

Accordingly, the first-first internal space A1-1 may serve as a buffer space that prevents external foreign matters from entering the first-second internal space A1-2 or prevents chemical fumes generated in the first-second internal space A1-2 during a sampling operation from being discharged to the outside when the first door 103 is opened.

The plurality of sampling lines L1, L2, and L3 may pass through the housing 100, for example, through an upper wall of the housing 100, such that discharge ports of the plurality of sampling lines L1, L2, and L3 are disposed in the first-second internal spaces A1-2.

The bottle holding unit 200 may hold the sample bottle B. The bottle conveying unit 250 may convey the bottle holding unit 200.

The bottle holding unit 200 may include a first bottle holding member 210 and a second bottle holding member 220. The bottle conveying unit 250 may include a first bottle conveying member 251 and a second bottle conveying member 252.

The first bottle holding member 210 may hold the sampling bottle B loaded into the first-first internal space A1-1.

The first bottle conveying member 251 may convey the first bottle holding member 210 in the X direction. The X direction (first direction) may be a horizontal direction.

The sampling bottle B held in the first-first internal space A1-1 by the first bottle holding member 210 may pass through the second inlet 121 and be transferred to the cap separating/coupling module 300 in the first-second internal space A1-2 by the first bottle transfer member 251.

The second bottle holding member 220 may hold the sampling bottle B transported to a position under the cap separating/coupling module 300 in a state where the sampling bottle B is held by the first bottle holding member 210.

The second bottle conveying member 252 may convey the second bottle holding member 220 in the Y direction. The Y direction (second direction) may be a horizontal direction parallel to or intersecting the X direction. For example, the X-direction and the Y-direction may intersect each other perpendicularly. Accordingly, the maximum width of the housing 100 may be minimized.

The sampling bottle B held by the second bottle holding member 220 may be conveyed by the second bottle conveying member 252 and disposed below the discharge ports of the plurality of sampling lines L1, L2, and L3.

The first vial holding section 210 may be separated from the sample vial B prior to the sample vial B being conveyed by the second vial conveying section 252. The second bottle holding member 220 may be separated from the sampling bottle B before the sampling bottle B is conveyed by the first bottle conveying member 251.

Accordingly, it is possible to prevent the body of the operator from coming into contact with the second bottle holding member 220, which may be contaminated by scattered or overflowed chemicals during filling of the sampling bottle B with the chemicals discharged from the sampling lines L1, L2 and L3.

The cover separation/coupling module 300 is coupled to the upper surface of the case 100. The cover separation/coupling module 300 may extend to the inner space of the housing 100, specifically, to the first-second inner spaces A1-2 through a through hole formed in the upper surface of the housing 100.

The cap separation/coupling module 300 may separate the cap C from the sampling bottle B and couple the cap C to the sampling bottle B. In this case, the sampling bottle B may be held by the first bottle holding member 210 and/or the second bottle holding member 220.

The discharge module 500 may have an inlet port to introduce chemicals into the interior space of the discharge module 500.

The inlet ports of the discharge module 500 may correspond in number and arrangement to the discharge ports of the plurality of sampling lines L1, L2, and L3. That is, the number of inlet ports formed in the discharge module 500 may be equal to the number of discharge ports of the plurality of sampling lines L1, L2, and L3. The plurality of inlet ports formed in the discharge module 500 may be arranged at the same interval as the discharge ports of the plurality of sampling lines L1, L2, and L3.

For example, when the sampling lines L1, L2, and L3 each have a discharge port and thus the number of discharge ports is equal to the number of sampling lines L1, L2, and L3, the inlet ports of the discharge module 500 may be equal in number to the sampling lines L1, L2, and L3.

As another example, when a plurality of sampling lines L1, L2, and L3 are connected in one line and thus only a single discharge port is disposed in the housing 100, the number of inlet ports of the discharge module 500 may be less than the number of sampling lines L1, L2, and L3. In this case, the number of sampling positions of the sampling bottle B can be reduced to one. Accordingly, the size of the housing 100 can be reduced, and by miniaturizing the discharge module 500 and simplifying the process of transporting the sampling bottle B, the effect of reducing the manufacturing and management costs can be expected.

The discharge module conveying unit 600 may convey the discharge module 500 such that the plurality of inlet ports of the discharge module 500 are disposed directly below the discharge ports of the plurality of sampling lines L1, L2, and L3.

For example, the discharge module conveying unit 600 may convey the discharge module 500 in the X direction, but the present disclosure is not necessarily limited thereto. The discharge module conveying unit 600 may convey the discharge module 500 in the Z direction. The Z direction (third direction) may be a vertical direction perpendicularly intersecting the X direction and the Y direction. In the latter case, the lowest position of the discharge module 500 may be disposed lower than the second bottle holding member 220.

Fig. 5 is a block diagram of a control unit, and fig. 6 to 10 are views illustrating a sampling process performed by a chemical sampling apparatus according to an embodiment of the present disclosure.

Referring to fig. 5, the chemical sampling apparatus 10 may include an input unit 700 and a control unit 710.

The input unit 700 may receive information about a chemical storage tank for collecting chemicals from an operator or the like.

The operator may use the input unit 700 and select one of the plurality of chemical storage tanks 3,5, and 6 (e.g., the first chemical storage tank 3) as a sampling target.

The input unit 700 may include a touch screen, but the present disclosure is not necessarily limited thereto.

The control unit 710 may control the bottle holding unit 200, the cap separating/coupling module 300, the bottle transporting unit 251, the second door 123, and the opening and closing valves V installed in the sampling lines L1, L2, and L3 such that the sampling bottles are filled with chemicals stored in the chemical storage tanks 3, 5, and 6 (e.g., the first chemical storage tank 3 designated by the input unit 700). Further, the control unit 710 may control the discharge module transferring unit 600 and the switching valve V such that the chemicals contained in the sampling lines L1, L2, and L3 connected to the chemical storage tanks 3, 5, and 6 designated by the input unit 700 (e.g., the sampling line L1 connected to the first chemical storage tank 3 designated by the input unit 700) are discharged to the discharge module 500 before the sampling bottle B is filled with the chemicals.

The sampling process and control logic of the control unit 710 will be described in detail below with reference to the accompanying drawings.

Referring to fig. 6 to 10, an operator may input a command for unlocking the first door 103 through the input unit 700. When a command for unlocking the first door 103 is input, the control unit 710 may control the door locking device 720 to unlock the first door 103.

When the first door 103 is unlocked, the operator may open the first door 103, place the sampling bottle B on the first bottle holding member 210 disposed in the first-first internal space A1-1, and then close the first door 103.

The sampling bottle B may be loaded and unloaded in a state where the cap C is coupled to the sampling bottle B. Thus, it is sufficient that the operator only wears the safety equipment with a general protection level, not the safety equipment with the highest protection level.

When a command for locking the first door 103 is input through the input unit 700, the control unit 710 may control the door locking device 720 to lock the first door 103.

However, the present disclosure is not necessarily limited thereto. The control unit 710 may lock the first door 103 according to a sensed value of a door sensor (not shown) that detects whether the first door 103 is closed.

The control unit 710 may maintain the locked state of the first door 103 until the operator unloads the sampling bottle B after the sampling operation is ended and the cap C is coupled to the sampling bottle B.

As shown in fig. 6, the control unit 710 may control the first vial holding section 210 to hold the sample vial B while changing the state of the first door 103 to the locked state.

Next, the operator may use the input unit 700 and select one chemical storage tank to collect chemicals. The control unit 710 may open an on-off valve V installed in a sampling line L1 connected to a chemical storage tank (e.g., the first chemical storage tank 3) for collecting chemicals for a predetermined time, and may operate the pump P to discharge the chemicals contained in the respective sampling lines L1 to the discharge module 500.

In this case, the control unit 710 may control the on-off valve installed in the supply pipe as described above such that the on-off valve installed in the supply pipe operates together with the on-off valve V installed in the sampling line L1.

The chemical contained in the sampling line L1 needs to be discharged to the discharge module 500 because the chemical contained in the sampling line L1 stagnates and forms deposits when a predetermined time elapses, and the chemical is highly likely to be contaminated by the opened discharge port. The venting operation may improve the reliability of the degree of contamination of the analytical chemistry.

Next, as shown in fig. 7, the control unit 710 may control the discharge module conveying unit 600 to convey the discharge module 500 in the X direction. The control unit 710 may open the second door 123 and then control the first bottle transporting member 251 to transport the sampling bottle B to a position below the first-second internal space A1-2, specifically, a position below the cap separating/coupling module 300. The control unit 710 may close the second door 123 and control the second bottle holding member 220 to hold the sampling bottle B. The control unit 710 may control the cap separation/coupling module 300 to separate the cap C from the sampling bottle B.

However, the present disclosure is not necessarily limited thereto. The control unit 710 may perform an operation of discharging chemicals using the discharge module 500 at the same time as or after the operation of separating the cap C. Alternatively, when the second bottle holding member 220 is rotated in a state where the cap C is held by the cap separating/coupling module 300, the cap C may be separated.

Next, as shown in fig. 8, the control unit 710 may separate the first vial holding part 210 from the sampling vial B, and then control the second vial conveying part 252 to convey the sampling vial B to a position below the discharge port of the sampling line L1. The control unit 710 may fill the sampling bottle B with the chemical stored in the first chemical storage tank 3 by opening the on-off valve V installed in the sampling line L1 and operating the pump P for a predetermined time. However, the present disclosure is not necessarily limited thereto. With the second bottle holding member 220 fixed, the control unit 710 may fill the sampling bottle B with the chemical by moving the sampling line L1 to a position above the sampling bottle B.

When some chemicals overflow during the operation of filling the sampling bottle B with chemicals, a chemical detection sensor (not shown) mounted on the first partition wall 110 or the second bottle holding member 220 may detect the overflow, and the control unit 710 may stop the sampling process and issue an alarm according to the sensed value of the chemical detection sensor.

Next, as shown in fig. 9, the control unit 710 may control the second bottle conveying member 252 to convey the sampling bottle B to a position under the cap separating/coupling module 300. The control unit 710 may control the first vial-holding section 210 to hold the sample vial B. The control unit 710 may control the cap separation/coupling module 300 to couple the cap C to the sampling bottle B. The control unit 710 may separate the cap holding unit 310 from the cap C and move the cap holding unit 310 upward to return the cap holding unit 310 to the original position. In this case, the control unit 710 may control the discharge module transporting unit 600 to return the discharge module 500 to the original position. Alternatively, when the second bottle holding member 220 is rotated in a state where the cap C is held by the cap separating/coupling module 300, the cap C may be coupled.

Next, as shown in fig. 10, the control unit 710 may separate the second bottle holding member 220 from the sampling bottle B, open the second door 123, and control the first bottle conveying member 251 to convey the sampling bottle B to the first-first internal space A1-1. Further, the control unit 710 may close the second door 123, separate the first bottle holding member 210 from the sampling bottle B, and control the door locking device 720 to unlock the first door 103.

Meanwhile, a chemical sensor (not shown) for measuring the concentration of chemical smoke may be disposed in the first-first inner space A1-1.

When the concentration of the chemical vapor detected by the chemical sensor is equal to or greater than a predetermined value, the control unit 710 may maintain the locked state of the first door 103 and operate the exhaust module 107 until the concentration of the chemical vapor becomes less than the predetermined value.

When the first door 103 is unlocked, the operator can open the first door 103 and then unload the sampling bottle B. The operator can place the sampling bottle B into a storage container, such as an ethylene plastic bag, and transport the sampling bottle B to a site for analysis of the contamination level of chemicals.

When the first door 103 is closed, the control unit 710 may change the state of the first door 103 to a locked state.

Fig. 11 is a perspective view of a delivery device including a first bottle holding member according to an embodiment of the present disclosure, and fig. 12 is a perspective view of the holding member shown in fig. 11.

Referring to fig. 11 and 12, a transfer device according to an embodiment of the present disclosure may include a first partition wall 110, a first bottle holding member 210, a transfer member 251, and a sealing unit 400.

The first partition wall 110 may partition a first space above the first partition wall 110 and a second space below the first partition wall 110. For example, the first partition wall 110 may be coupled to a housing (not shown) and divide an inner space of the housing into a first space and a second space.

The first partition wall 110 may be provided in the form of a plate extending in the X-direction and the Y-direction, but the present disclosure is not necessarily limited thereto. The Y direction (second direction) may be a direction perpendicular to the X direction (first direction). The Y direction may be a horizontal direction or a vertical direction.

The guide slit 111 may be formed in the first partition wall 110.

The guide slit 111 may penetrate the first partition wall 110 in the Z direction and extend in the X direction. The Z direction (third direction) may be a direction perpendicular to the X direction and the Y direction.

The first bottle holding member 210 may hold a delivery target, such as a sampling bottle B containing a chemical.

However, the present disclosure is not necessarily limited thereto. The sample vial B may simply be placed or secured to the first vial holding section 210.

The first bottle holding member 210 may include a pair of grippers 210a and a spacing adjustment member 223.

The pair of grippers 210a may be arranged to be spaced apart from each other in the X direction. The interval between the pair of grippers 210a in the X direction can be adjusted by the interval adjusting part 223.

The holder 210a may include a seating portion 211 on which the sampling bottle B is seated, a side supporting portion 213 configured to support a side surface of the sampling bottle B, and an arm 215 extending from the seating portion 211 or the side supporting portion 213 to the interval adjusting part 223.

The seating portion 211 and the side supporting portion 213 may be disposed in the first space, and the arm 215 may extend from the first space to the second space through the guide slit 111. Accordingly, the sampling bottle B held by the seating portion 211 and the side supporting portion 213 may be disposed in the first space. However, the interval adjusting member 223 and the driving device (such as a conveying member 251 to be described later) may be disposed in the second space and be free from exposure to chemicals or fumes.

The conveying member 251 may convey the first bottle holding member 210 in the X direction.

The conveying member 251 and/or the interval adjusting member 223 may include a pneumatic cylinder or a hydraulic cylinder, but the present disclosure is not necessarily limited thereto. The conveying member 251 and/or the interval adjusting member 223 may include various driving devices, such as a motor.

The conveying member 251 may be coupled to the first bottle holding member 210 by a bottle lifting member 253.

The conveying member 251 may convey the bottle lifting member 253 in the X direction, and the bottle lifting member 253 may convey the first bottle holding member 210 in the Z direction.

After the first bottle holding member 210 is separated from the sampling bottle B, the first bottle holding member 210 may be moved downward by the bottle lifting member 253 before the second bottle conveying member 252 conveys the sampling bottle B.

The conveying member 251 and the bottle lifting member 253 may each include a hydraulic cylinder or a pneumatic cylinder, but the present disclosure is not necessarily limited thereto.

The conveying member 251 and the bottle lifting member 253 may be disposed in the second internal space A2. Thus, it is possible to prevent the driving means such as the conveying member 251 and the bottle lifting member 253 from being exposed to chemicals and minimize corrosion caused by the exposure to chemicals.

The sealing unit 400 may close the region of the guide slit 111 through which the first bottle holding member 210 passes.

Accordingly, other than the region of the guide slit 111 in which the first bottle holding member 210 is disposed, the remaining region of the guide slit 111 may be closed by the sealing unit 400, so that movement of chemicals or fumes through the guide slit 111 may be maximally suppressed.

The sealing unit 400 may include a pair of first shields 410.

The pair of first shields 410 may be disposed at positions spaced apart from each other in the Y direction and coupled to the first partition wall 110. The guide slit 111 may be disposed between the pair of first shields 410.

Thus, the arm 215 of the first bottle holding member 210 can move between the pair of first shields 410.

The pair of first shields 410 may be detachably coupled to each other.

To this end, the pair of first shields 410 may have different magnetic properties.

For example, one of the pair of first shields 410 may include an N-pole permanent magnet and the other of the pair of first shields 410 may include an S-pole permanent magnet.

Accordingly, the pair of first shields 410 may be coupled to each other by a magnetic force to close the guide slit 111. The arm 215 of the first bottle holding member 210 may move along the guide slit 111 while separating the pair of first shields 410. After the arm 215 passes through the portion between the pair of first shields 410, the pair of first shields 410 separated from each other by the arm 215 may be coupled to each other again by magnetic force.

The pair of first shields 410 may be made of a flexible material, but the present disclosure is not necessarily limited thereto.

Fig. 13 is a cross-sectional view of the tapered region shown in fig. 12.

Referring to fig. 12 and 13, the arm 215 may include a tapered region 215a in contact with the pair of first shields 410.

The tapered region 215a may have a cross-sectional shape whose width in the Y direction decreases toward both opposite ends of the first bottle holding member 210 in the X direction.

Accordingly, when the arm 215 moves, the pair of first shields 410 can be easily separated from each other, and the pair of first shields 410 can be maximally brought into close contact with the arm 215.

The gripper 210a may include a pair of rollers 217 coupled to the arm 215 so as to be rotatable about a rotation axis formed in the Z direction.

For example, the bracket 217a may be coupled to the arm 215, and the pair of rollers 217 may be rotatably coupled to the bracket 217a.

The pair of rollers 217 may be disposed on each of two opposite ends of the first bottle holding member 210 in the X direction.

The pair of rollers 217 may be arranged to be spaced apart from each other in the Y direction. As the pair of first shields 410 pass between the pair of rollers 217, the spacing between the pair of first shields 410 may be reduced. Accordingly, the pair of first shields 410 can be maximally brought into close contact with the arm 215, and the pair of rollers 217 can assist in the re-coupling operation of the pair of first shields 410.

Fig. 14 is a view showing a modified example of the sealing unit.

Referring to fig. 12 and 14, the sealing unit 400 may include a pair of second shields 420.

Similar to the pair of first shields 410, the pair of second shields 420 may be disposed at positions spaced apart from each other in the Y direction and coupled to the first partition wall 110. The guide slit 111 may be disposed between the pair of second shields 420.

Thus, the arm 215 of the first vial holder member 210 may be moved between the pair of second shields 420.

The pair of second shields 420 may be detachably coupled to each other.

For this, a protrusion 421 extending in the X direction may be formed on one of the pair of second shields 420, and a groove 423 coupled with the protrusion 421 may be formed on the other of the pair of second shields 420.

Accordingly, when the protrusion 421 is inserted into the groove 423, the pair of second shields 420 may close the guide slit 111. The arm 215 of the first bottle holding member 210 may move along the guide slit 111 while separating the pair of second shields 420. After the arm 215 passes through the portion between the pair of second shields 420, the pair of second shields 420 separated from each other by the arm 215 may be coupled to each other again when the protrusion 421 is inserted into the groove 423.

However, the present disclosure is not necessarily limited thereto. The plurality of protrusions 421 may be arranged in the X direction.

The pair of second shields 420 may be made of a flexible material, but the present disclosure is not necessarily limited thereto.

As the pair of second shields 420 passes between the pair of rollers 217 rotatably coupled to the arm 215, the spacing between the pair of second shields 420 may be reduced. Accordingly, the pair of rollers 217 may press the pair of second shields 420 and assist the insertion of the protrusions 421 into the grooves 423.

Fig. 15 is a view showing another modified example of the sealing unit.

Referring to fig. 15, the sealing unit 400 may include a pair of rollers 430, a pair of films 440, and a rotational force supply member 450.

The pair of rollers 430 may be disposed at positions spaced apart from each other in the X direction and rotatably coupled to the first partition wall 110. The guide slit 111 may be disposed between the pair of rollers 430.

For example, the pair of rollers 430 may be disposed at both opposite ends of the guide slit 111 in the X direction.

The membrane 440 may be wound around the drum 430 and coupled to the arm 215 of the first bottle holding member 210 by fastening means (e.g., bolts, adhesive, etc.).

The film 440 may be disposed on the guide slit 111 and disposed parallel to the first partition wall 110.

The rotational force supply member 450 may provide a rotational force to the drum 430 such that the drum 430 rotates in a direction in which the film 440 is wound.

Accordingly, when the first bottle holding member 210 is conveyed by the conveying member 251, the film 440 disposed rearward from the first bottle holding member 210 is unwound from the drum 430, but the film 440 disposed forward from the first bottle holding member 210 is wound around the drum 430 by the rotational force supply means 450. Accordingly, the remaining area of the guide slit 111 except for the area of the guide slit 111 in which the first bottle holding member 210 is disposed may be held closed by the pair of films 440.

The rotational force supply member 450 may include an elastic member, such as a spring, coupled to the first partition wall 110 and the rotation shaft of the drum 430.

However, the present disclosure is not necessarily limited thereto. The rotational force supply member 450 may include a control motor or the like for providing a rotational force to the drum 430 to provide a predetermined tension to the film 440.

Fig. 16 is a perspective view of the second bottle holding member, and fig. 17 is a vertical sectional view of the second tapered region.

Referring to fig. 4, 16 and 17, the second bottle holding member 220 may include a pair of second grippers 221 and a second interval adjusting member 223.

The pair of second holders 221 may be arranged to be spaced apart from each other in the Y-direction. The second interval adjustment part 223 adjusts the interval in the Y direction between the pair of second holders 221 so that the pair of second holders 221 hold the sampling bottle B or separate the sampling bottle B.

The second interval adjustment member 223 may include a hydraulic cylinder or a pneumatic cylinder, but the present disclosure is not necessarily limited thereto.

The second gripper 221 may include a second seating portion 221a on which the sampling bottle B is seated, a second side supporting portion 221B configured to support a side surface of the sampling bottle B, and a second arm 221c extending from the second interval adjusting part 223 to the second side supporting portion 221B in the X direction.

The second arm 221c may be disposed to pass through the second guide slit 131 formed in the third partition wall 130.

The second guide slit 131 may penetrate the third partition wall 130 in the X direction and extend in the Y direction to guide the movement of the second bottle holding member 220 in the Y direction.

The second seating part 221a and the second side supporting part 221b of the second bottle holding member 220 may be disposed in the first-second inner space A1-2, and the second interval adjusting member 223 may be disposed in the third inner space A3. Accordingly, it is possible to prevent the driving device (such as the second interval adjustment member 223) from being exposed to the chemical and minimize corrosion caused by the exposure to the chemical.

Meanwhile, a pair of second shields 411 may be coupled to the third partition wall 130.

The pair of second shields 411 may be disposed to face each other with respect to the second guide slit 131, and made of a flexible material. The pair of second shields 411 may include permanent magnets having different magnetic properties.

For example, one second shield 411 may comprise an N-pole permanent magnet and the other second shield 411 may comprise an S-pole permanent magnet.

The pair of second shields 411 may be coupled to each other by a magnetic force to close the second guide slit 131. The second arm 221c may move along the second guide slit 131 while separating the pair of second shields 411. After the second arm 221c passes through the portion between the pair of second shields 411, the pair of second shields 411 separated from each other may be coupled to each other again by magnetic force. Accordingly, inflow or outflow of chemicals or chemical fumes through the second guide slit 131 can be suppressed.

The second gripper 221 may include a pair of second rollers 221d coupled to the second arm 221c so as to be rotatable about a rotation axis formed in the X direction.

For example, the second bracket 221e may be coupled to the second arm 221c, and the pair of second rollers 221d may be rotatably coupled to the second bracket 221e.

The pair of second rollers 221d may be arranged to be spaced apart from each other in the Z direction, and to be spaced apart from the second arm 221c in the Y direction. The pair of second shields 411 may be disposed between the pair of second rollers 221 d. Accordingly, the pair of second rollers 221d may assist the re-coupling operation of the pair of second shields 411 such that the area where the pair of second shields 411 are separated from each other may be minimized to the area where the second arm 221c is arranged.

The second arm 221c may include a second tapered region 221f contacting the pair of second shields 411.

The second tapered region 221f may have a vertical cross-sectional shape whose width in the Z direction increases with an increase in the distance from the pair of second rollers 221d in the Y direction. Accordingly, the pair of second shields 411 can be brought into close contact with the second arm 221c to the greatest extent and cooperate with the pair of second rollers 221d to minimize the opening area of the second guide slit 131.

The second bottle conveying member 252 may be coupled to the third partition wall 130 and convey the second bottle holding member 220 in the Y direction.

The second bottle conveying member 252 may include a servo motor, but the present disclosure is not necessarily limited thereto.

The second bottle conveying member 252 may be disposed in the third inner space A3. Thus, the drive device (such as the second bottle delivery member 252) may be protected from exposure to the chemical and corrosion caused by exposure to the chemical may be minimized.

Fig. 18 is a perspective view of the cover separating/coupling module, fig. 19 is an exploded perspective view of fig. 18, fig. 20 and 21 are views for explaining an operation principle of the cover holding unit, fig. 22 is a partially enlarged view of fig. 20, and fig. 23 is a partially enlarged view of fig. 21.

Referring to fig. 18 to 21, the cover separating/coupling module 300 may include a cover holding unit 310, a cover rotating unit 320, and a cover lifting unit 330, and may further include a lifting frame 340 and/or a cover 350.

The cover holding unit 310 may hold the cover C. To this end, the cover holding unit 310 may include a first frame 311, a plurality of grippers 312, a second frame 313, a plurality of links 314, and a frame lifting part 315, and may further include a plate member 318 and a plurality of elastic members 319.

A plurality of holders 312 may be rotatably coupled to the first frame 311 so as to support the side surface of the cover C.

The second frame 313 may be disposed in a horizontal plate region of the first frame 311 and is conveyed in a vertical direction (i.e., Z direction) by the frame lifting member 315.

The number of links 314 may be equal to the number of grippers 312, and may be three, for example. The links 314 may each be rotatably coupled to the holder 312 and the second frame 313. The vertical rectilinear motion of the second frame 313 may be converted into rotational motion of the clamper 312 by the link 314.

For example, as shown in fig. 20, the plurality of grippers 312 are rotated forward such that the gripping surfaces thereof are moved away from each other when the second frame 313 is moved upward, so that the plurality of grippers 312 can be separated from the cover C. As shown in fig. 21, the plurality of grippers 312 are reversely rotated such that the gripping surfaces thereof are moved close to each other when the second frame 313 is moved downward, so that the plurality of grippers 312 can hold the cover C.

The frame lifting member 315 may be coupled to the first frame 311 and convey the second frame 313 in the Z-direction.

The frame lifting member 315 may include a pneumatic cylinder, but the present disclosure is not necessarily limited thereto. The frame lifting member 315 may include other lifting devices such as hydraulic cylinders.

The plate member 318 may be disposed below the first frame 311, and coupled to the first frame 311 so as to be vertically movable.

A plurality of elastic members 319 may be interposed between the first frame 311 and the plate member 318, and provide elastic force to the plate member 318 such that the plate member 318 is maintained in a horizontal state.

For example, the plurality of elastic members 319 may be arranged to be spaced apart from each other in the horizontal direction.

The lower surface of the plate member 318 may be disposed to face the upper surface of the cover C held by the plurality of holders 312.

Therefore, when the cap holding unit 310 moves upward or downward, it is possible to suppress the cap holding unit 310 from being damaged due to collision with the sampling bottle B or the cap C. Further, even if the sampling bottle B is partially inclined, the state of the sampling bottle B can be changed to the upright state.

The cover rotating unit 320 may be mounted on the lifting frame 340 and rotate the cover holding unit 310 (e.g., the frame lifting member 315) about a rotation axis in the Z-direction.

The cover rotating unit 320 may include a servo motor, but the present disclosure is not necessarily limited thereto.

The cover lifting unit 330 may convey the lifting frame 340 in the Z-direction (i.e., the vertical direction).

Accordingly, the cover holding unit 310 together with the lifting frame 340 may also be conveyed in the Z-direction by the cover lifting unit 330.

Further, the cover holding unit 310 may be moved downward by the cover lifting unit 330, and then hold the cover C. Further, the cap holding unit 310 may be rotated and moved upward by the cap rotating unit 320 and the cap lifting unit 330, and separate the cap C from the sampling bottle B. The process of coupling the cap C to the sampling bottle B may be performed in reverse order.

The cover lifting unit 330 may be coupled to an upper surface of the case 100. The frame lifting part 315, the cover rotating unit 320, and the cover lifting unit 330 may be disposed outside the housing 100. The frame lifting part 315 may extend to the first-second inner spaces A1-2 through a through hole formed in the upper wall of the housing 100. It is possible to prevent the driving means, such as the cover rotating unit 320 and the cover lifting unit 330, from being exposed to the chemical fumes and to minimize corrosion caused by the exposure to the chemical fumes.

The cover lifting unit 330 may include a pneumatic cylinder, but the present disclosure is not necessarily limited thereto.

The lifting frame 340 may include a cylinder holder 341 configured to support the cylinder 316 constituting the frame lifting member 315 such that the cylinder 316 is rotatable.

For example, the frame lifting member 315 may include a cylinder 316 and a piston 317.

The air cylinder 316 may be coupled to the first frame 311 and the rotation shaft of the cover rotation unit 320, and rotated by the cover rotation unit 320.

The cylinder 316 may include a first cylinder region 316a and a second cylinder region 316b disposed above the first cylinder region 316 a.

The first chamber C1 may be formed in the first cylinder region 316a, the second chamber C2 may be formed in the second cylinder region 316b, and the piston 317 may be disposed in the first chamber C1.

The piston 317 may include a first rod 317a passing through a lower wall of the cylinder 316 and coupled to the second frame 313, and a second rod 317b passing through a partition wall between the first and second chambers C1 and C2 and extending to the second chamber C2. The first rod 317a may protrude from a lower surface of the piston 317, and the second rod 317b may protrude from an upper surface of the piston 317.

The piston 317 may be moved in a vertical direction by the fluid supplied into the first chamber C1.

To this end, the cylinder holder 341 may have a first fluid port 341a and a second fluid port 341b to which fluid supply lines (not shown) are coupled. The first and second fluid ports 341a and 341b may extend to the inner circumferential surface of the cylinder holder 341. The second cylinder region 316b may have a first through hole 316b-1 and a second through hole 316b-2 extending from an outer circumferential surface of the second cylinder region 316b to the second chamber C2. A first flow path 317a-1 may be formed in the piston 317 and connected to the first through hole 316b-1. The first flow path 317a-1 may extend to an outer circumferential surface of an upper end portion of the first lever 317 a. A second flow path 317b-1 may be formed in the piston 317 and connected to the second through hole 316b-2. The second flow path 317b-1 may extend to an outer circumferential surface of a lower end portion of the second rod 317 b.

The fluid injected through the first fluid port 341a may be supplied to the lower side of the first chamber C1 through the first through hole 316b-1, the first flow path 317a-1, and the first through flow path 317a-2 in sequence. Thus, the piston 317 may move upward or downward.

The fluid injected through the second fluid port 341b may be sequentially supplied to the upper side of the first chamber C1 through the second through-hole 316b-2, the second flow path 317b-1, and the second through-flow path (317 b-2). Thus, the piston 317 may move downward.

An annular first groove 316b-3 and an annular second groove 316b-4 may be formed in the outer circumferential surface of the second cylinder region 316 b.

When the cylinder 316 rotates, the first and second grooves 316b-3 and 316b-4 maintain the first and second through holes 316b-1 and 316b-2 connected to the first and second fluid ports 341a and 341b, respectively.

However, the present disclosure is not necessarily limited thereto. The first groove 316b-3 and the second groove 316b-4 may be formed in an inner circumferential surface of the cylinder holder 341.

The recess R may be formed in the lower and upper surfaces of the first cavity C1 and abut on the outer circumferential surface of the first lever 317a or the second lever 317 b.

Accordingly, even if the piston 317 reaches a height equal to or close to the height of the lower surface or the upper surface of the first chamber C1, the first flow path 317a-1 or the second flow path 317b-1 may remain connected to the first chamber C1.

The cover 350 may be coupled to the upper surface of the housing 100 and the cylinder holder 341, and provided in the form of a flexible pipe to surround the through hole formed in the housing 100. The frame lifting member 315 may be disposed in the cover 350. For example, the cover 350 may be a corrugated tubing.

Therefore, the inflow or outflow of the chemical fumes through the through-hole of the case 100 can be suppressed.

Referring to fig. 22 and 23, although the piston 317 moves upward or downward, the first through hole 316b-1 formed in the cylinder 316 may remain connected to the first flow path 317a-1 formed in the piston 317, and the second through hole 316b-2 formed in the cylinder 316 remains connected to the second flow path 317b-1 formed in the piston 317.

To this end, the stroke of the piston 317 (i.e., the interval in the Z direction between the top dead center (see fig. 20) and the bottom dead center (see fig. 21) of the piston 317) may be smaller than the sum of the outlet diameter d1 of the first through hole 316b-1 and the inlet diameter d2 of the first flow path 317a-1 and smaller than the sum of the outlet diameter d3 of the second through hole 316b-2 and the inlet diameter d4 of the second flow path 317 b-1.

Fig. 24 is a perspective view of the discharge module, fig. 25 is an exploded perspective view of fig. 24, and fig. 26A is a front view of the discharge module.

Referring to fig. 24 and 25, the discharge module 500 may include a housing 510 having a single inlet port 510a or a plurality of inlet ports 510a formed in an upper surface thereof, and a discharge duct 520 and a supply duct 530 connected to the housing 510.

As described above, the plurality of inlet ports 510a may correspond in number and arrangement to the plurality of sampling lines L1, L2, and L3.

The chemical collected in the inner space of the housing 510 through the inlet port 510a of the housing 510 may be discharged to the outside of the housing 100, for example, to a chemical purifying facility (not shown) or the like through the discharge duct 520.

A diluting solution (e.g., water) may be supplied to the inner space of the housing 510 through the supply pipe 530. To this end, the supply pipe 530 may be connected to a diluting solution supply device (not shown) disposed outside the housing 100.

The discharge duct 520 and the supply duct 530 may each be provided in the form of a flexible tube (flexible tube) and coupled to a through hole formed in a sidewall of the housing 100.

A second valve V2 (see fig. 27) may be installed in the supply pipe 530, and the second valve V2 may be controlled by the control unit 710 (see fig. 27) so as to operate together with the first valve V1 installed in the sampling lines L1, L2, and L3.

For example, the first valve V1 installed in the sampling lines L1, L2 and L3 may be opened for a predetermined time to discharge the chemicals contained in the sampling lines L1, L2 and L3 to the discharge module 500 before filling the chemical into the sampling bottle B. In this case, the second valve V2 installed in the supply pipe 530 may also be opened. Accordingly, after discharging the chemicals contained in the sampling lines L1, L2 and L3 to the discharge module 500, the sampling bottle B may be filled with the chemicals stored in the chemical storage tank. The chemicals collected in the discharge module 500 may be mixed with the diluted solution and then discharged in a diluted state. Meanwhile, when a predetermined time elapses after the first valves V1 installed in the sampling lines L1, L2 and L3 are closed, the second valve V2 installed in the supply pipe 530 is closed, so that a cleaning operation of discharging the remaining chemicals in the discharge module 500 can be performed.

However, the present disclosure is not necessarily limited thereto. Depending on the chemical nature, the second valve V2 may be opened a predetermined time after the first valve V1 is closed, or the second valve V2 may remain closed before and after the first valve V1 is closed. For example, when the chemical is an undiluted sulfuric acid solution, the mixture of undiluted sulfuric acid solution and water generates excessive heat, which can adversely affect the overall apparatus.

The delivery unit 600 may include a delivery device, such as a pneumatic cylinder 610 and a cover 620. However, the present disclosure is not necessarily limited thereto, and the conveying device may include a hydraulic cylinder, a motor, or the like.

The pneumatic cylinder 610 may be coupled to the third partition wall 130 and disposed in the third space (i.e., the third internal space A3). The piston rod 610a (i.e., the connection member of the pneumatic cylinder 610) may extend through a through-hole formed in the third partition wall 130 and be coupled to the housing 510 disposed in the first space (i.e., the first internal space, specifically, the first-second internal spaces A1-2). Thus, the drive device (e.g., pneumatic cylinder 610) may be protected from exposure to chemical fumes and corrosion caused by exposure to chemical fumes may be minimized.

The cover 620 may prevent chemical fumes from flowing in or out through the through-holes formed in the third partition wall 130.

The cover 620 may be provided in the form of a flexible tubing, such as corrugated tubing. The two opposite ends of the cover 620 may be coupled to the third partition wall 130 and the housing 510, and the piston rod 610a may extend through the cover 620.

Referring to fig. 26a, the inlet port 510a of the housing 510 may be disposed higher than the seating surface of the second bottle holding member 220 on which the sampling bottle B is seated.

For example, the height h1 from the upper surface of the housing 510 to the discharge ports of the sampling lines L1, L2, and L3 may be smaller than the height h2 from the seating surface of the second bottle holding member 220 to the discharge ports of the sampling lines L1, L2, and L3. The upper surface of the housing 510 or the inlet port 510a may be disposed at substantially the same height as the opening of the upper end of the sampling bottle b.

Accordingly, it is possible to minimize the chemical drop distance from the discharge ports of the sampling lines L1, L2 and L3 to the inlet port 510a of the housing 510 and minimize the scattering of chemicals.

Fig. 26b is a view showing a first modified example of the exhaust module, and fig. 26c and 26d are views showing a second modified example of the exhaust module.

The configuration of the discharge module 500 and sampling lines L1, L2 and L3 may be variously modified. Referring to fig. 26b, the sampling lines L1, L2, and L3 may be spaced apart from the discharge module 500 at predetermined intervals in the vertical direction. Thus, the second bottle holding member 220 can freely move between the discharge module 500 and the sampling lines L1, L2, and L3.

In this case, the size of the inlet port 510a may be appropriately adjusted so that the chemicals discharged from the sampling lines L1, L2 and L3 may be introduced into the discharge module 500 without being scattered. Alternatively, the cover with the inlet port may be omitted. The advantage of this configuration is that the drive unit can be omitted.

Referring to fig. 26c, the sampling lines L1, L2 and L3 may be moved up or down by separate driving units. This configuration can minimize the chemical drop distance as the sampling lines L1, L2 and L3 move downward when the chemical is discharged, thereby suppressing scattering.

Further, as shown in fig. 26d, when the chemical is completely discharged, the sampling lines L1, L2 and L3 may be moved upward, and the second bottle holding member 220 may be moved between the discharge module 500 and the sampling lines L1, L2 and L3.

However, the present disclosure is not necessarily limited thereto. The drain module 500 may be moved up or down in a state where the sampling lines L1, L2 and L3 are fixed. Alternatively, all sampling lines L1, L2, and L3, as well as the discharge module 500, may be moved up or down. Alternatively, the chemicals may be collected as the sampling lines L1, L2, and L3 and/or the discharge module 500 move forward or backward. Any configuration may be applied without limitation as long as the discharge module 500 can collect chemicals without restricting movement of the second bottle holding member 220.

The embodiments have been described above, but these embodiments are merely illustrative and are not intended to limit the present disclosure. Those skilled in the art will appreciate that various modifications and changes not described above may be made without departing from the inherent features of the present disclosure. For example, the respective constituent elements specifically described in the embodiments may be modified and then executed. Furthermore, it is to be understood that variations relating to modifications and applications are included within the scope of the present disclosure as defined by the appended claims.
